An overview is presented of the physical principles of PET scanning and the inherent limitations of this technology to set the basis for the critical interpretation of PET data presented in the second and third parts and in the ever-increasing number of PET studies on the brain in different physiological and pathological conditions. Finally, the authors describe the ability to measure in vivo regional cerebral glucose metabolism with [18F]-FDG PET, regional cerebral blood flow and the distribution and binding capacity of neuroreceptors. They conclude with future perspectives of PET technology and its relevance, especially for neuropsychiatric research. Y1 - 1998/// IS - 3 AV - none SP - 161 ER -
